Comparison of the aroma profiles of hops using dynamic headspace sampling with TD–GC–TOF MS

This study demonstrates the high performance of a dynamic headspace sampler with TD–GC–TOF MS analysis for investigating the complex aroma profiles from three varieties of hops.

The sampler was a Micro-Chamber/Thermal Extractor from Markes International, which allows up to six samples to be taken simultaneously at elevated temperature for faster sampling. The use of Tandem Ionisation provides enhanced confidence in the identification of terpenoids, while the comparison of hop varieties is simplified by real-time data-processing in the accompanying software package.
